Meningiomas occurring in the skin are rare and may be difficult to recognize on frozen section. We found intraoperative cytologic smears helpful in identifying the characteristically bland nuclei, cellular whorls, and psammoma bodies that are typical of the light microscopy of meningiomas in the CNS. This case (a scalp lesion) was also examined ultrastructurally. Cutaneous meningiomas are histologically and ultrastructurally identical to their meningeal counterparts and must be approached with caution surgically.
发生于皮肤的脑膜瘤罕见，在冰冻切片上可能难以识别。我们发现术中细胞学涂片有助于识别脑膜瘤典型的温和细胞核、细胞漩涡和砂粒体，这些特征在中枢神经系统脑膜瘤的光学显微镜检查中很典型。该病例（头皮病变）也进行了超微结构检查。皮肤脑膜瘤在组织学和超微结构上与其脑膜对应物相同，手术时必须谨慎处理。
